I'm curious what you classify as a business ISP?

Take a look at AMS-IX, one of the largest internet exchanges: https://bgp.tools/ixp/AMS-IX

21/1020 (2%) of all peers are Mikrotik. 15 (1.4%) of those are >=1000mbps. 7 (0.6%) of those are 10gbps. None are larger than 10gbps.

You're referencing backbone, not edge. It has only been a few years that MikroTik had offered a 100G solution, let alone became competitive in it. You won't find it in the backbone yet. However, many European ISP's have largely upgraded their distro and aggregation switches to MikroTik over the last five years. There's a sovereignty push, too. I would guess edge is similar, but there's too many cheap options there so probably not that much.

If your impression is based on data circa ~2020, you should re-evaluate your priors with the recent packages in mind. See https://mikrotik.com/product/crs812_ddq

CE (Customer Edge) is what you are referring to. ISPs would be the PE (Provider Edge). I am aware it can be popular for SMB CE devices, however that is simply not the case for PE devices.

Service Provider ISPs cannot use Mikrotik - It is impossible. RouterOS supports none of the features required for a service provider. VRFs are even still unsupported in HW [1]. I am confused why this is even a discussion as anyone with experience working at an ISP/SP would come to the same conclusion.

Those selling end services to businesses.

I have a mix of equipment from heavyweight juniper mxs at peeing points to arista dcs/ccs in large sites to £50 mikrotiks in the smallest branch offices.

Right tool for the right job, mikrotik is often but not always the right tool.

Mikrotik can be popular for CE (Customer Edge) devices, that is correct. Those are not ISPs however, those are customers.
